String tempDirectoryName = "C:" + File.separator + "test";
File tempDirectory = new File(tempDirectoryName);
for (int i = 0; i < 10; i++) {
try {
File thisFile =
File.createTempFile("tmp", null, tempDirectory);
} catch (Exception e) {
System.out.println("Couldn't create temp file " + i);

The
createTempFile
method guarantees that each temp file created during the life of the program
will be different. It doesn't guarantee that the file names will mean anything to a human. Listing 8-6
shows the names of the files that program created in our
test
directory.
